disadvantage is that it also keeps out ______.

a. Viruses… most nutrients
b. Small molecules… fat – soluble molecules
c. Harmful gases… oxygen
d. Waste products… water

,7. Which of these chemicals cross the blood – brain barrier by active transport?

c. Proteins
d. Viruses

8. What makes brain cancers so difficult to treat?

a. Nearly all chemotherapy drugs fail to cross the blood – brain barrier
b. Brain cancers spread more rapidly than other cancers
c. The brain includes more pain receptors than other organs
d. The brain has a very low metabolic rate

9. What is the brain’s main source of fuel?

c. Thiamine
d. Proteins

1 When the neuron’s membrane is at rest, sodium ions are more concentrated _____
the cell, and potassium ions are more concentrated _____

a. Inside… outside
b. Inside… inside
c. Outside… inside
d. Outside… outside

2. When the membrane is at rest, the concentration gradient tends to draw potassium
ions _____ the cell, and the electrical gradient draws them ______ the cell.

a. Into… out of
b. Into… into
c. Out of… into
d. Out of… out of

3. When the membrane is at rest, the concentration gradient tends to draw sodium ions
____ the cell, and the electrical gradient draws them ___ the cell.

a. Into… out of
b. Into… into
c. Out of… into
d. Out of… out of

,4. The sodium – potassium pump moves sodium ions ____ and moves potassium ions
_____.

a. Into the cell… out of the cell
b. Into the cell… into the cell
c. Out of the cell… into the cell
d. Out of the cell… out of the cell

5. Suppose a neuron has a resting potential of –70mV. If the potential goes to –80mV,
the change would be a _____

a. Depolarisation
b. Hyperpolarisation

6. Under what conditions does an axon produce an action potential?

a. Whenever the membrane is hyperpolarised
b. Whenever the membrane’s potential reaches the threshold
c. Whenever the membrane is depolarised
d. Whenever the membrane’s potential reaches zero

7. During the rising portion of the action potential, which ions are moving across the
membrane and in which direction?

a. Sodium ions move out
b. Sodium ions move in
c. Both sodium and potassium ions move in
d. Potassium ions move in

8. After the action potential reaches its peak, the potential across the membrane falls
toward its resting level. What accounts for this recovery?

a. The sodium – potassium pump removes the extra sodium
b. Potassium ions move our because their channels are open and the electrical
gradient pushes them out
c. Potassium ions move out because their channels are open and the concentration
gradient pushes them out
d. Potassium ions move in
9. Which of the following is one way of stating the all-or-nothing law?

a. The amplitude of the action potential in one axon is the same as that in another
axon
b. At a given time, either all axons produce action potentials, or none do

potentials
